EXPERIMENTAL FACILITIES AT THE 2 MV VAN DE GRAAFF ACCELERATOR

Two beamlines are installed at the 2 MeV van de Graaff accelerator:

GONNY

GONNY consists of a large scattering chamber with a computer-controlled
4- axis - goniometer for standard RBS and NRA analyses incl. channeling.
Samples can be introduced with a simple load lock system. The data acquisition
accepts up to eight detectors simultanously. One detector is mounted on
a precision rotational stage and can be used for double alignement
measurements.
Heating or cooling stages are not provided at this goniometer.

GOLF

The second beamline is terminated with a standard 500 mm diam. scattering
chamber.
An accurate, computer - controlled three-axis goniometer is utilized
for channeling experiments and for He – ERDA of hydrogen.
